Show original supplier description
The Flagship One 37820-PM8-H02 is a guaranteed replacement Engine Computer, also known as an Engine Control Module (ECM), Engine Control Unit (ECU), or Powertrain Control Module (PCM). This unit is specifically designed for the 1989 Honda CRX with a 1.5L engine and the matching part number 37820-PM8-H02. This ECM arrives programmed and updated to your vehicle's specific VIN (Vehicle Identification Number), ensuring a true Plug and Play installation with no need for further programming. To facilitate this, you will be prompted to enter your VIN during the checkout process in the designated field. If your VIN is not immediately available, it can be provided later via email to admin@fs1inc.com or by phone at 516-766-2223 (EXT 2). Each unit undergoes rigorous quality control testing and refurbishment by certified in-house mechanics. This comprehensive in-house process ensures that every unit is inspected and prepared to address common PCM issues such as electrical problems, failure to start, fault codes, intermittent issues, loss of power, no ignition or injector pulse, poor fuel economy, and shifting problems. Flagship One offers a free lifetime warranty and free domestic shipping with quick turnaround times. Additionally, there is no core charge, meaning you can keep your old unit.
